沙河石头岭险工的治理对漯河市及其下游广大地区人民群众生命财产安全具有重大意义。根据现场调查和分析,决定采用“丁坝加护坡”方式,并通过河工模型试验进行具体方案选择。以所提出的方案选择原则为依据,经过对3种流量情况下整体定床试验初始方案和修正方案流态流势及流速分布的比较,确定了推荐方案。最后进行了局部动床试验,提出了该方案工程实施的具体措施和要求。 The management of the Shahedinglite insurer is of great significance to the safety of life and property of the people in the vast area of ​​Luohe City and its downstream areas. According to the on-site investigation and analysis, it is decided to adopt the mode of “dams plus slope protection” and select specific plans through river model tests. Based on the proposed principle of program selection, the recommended schemes were determined by comparing the flow patterns and flow velocities between the initial scheme and the revised scheme of the overall fixed bed test under the three kinds of flow conditions. At last, the local moving bed experiment was carried out, and the specific measures and requirements for the project implementation were put forward.
